Rbp are supposed to max out at around 12" which is ibet is rare for aquariums.anyhow who has rbp 10" or bigger? What have they been fed, and the tank size.currently I have only 1 adult rbp at 10" mark. Oddly enough this rbp was fed feeders n nightcrawlers and in a 20h aquarium when I bought him at 8". In the last year he's been in a 135gal n has grown 1.5"-2". I'm really starting to think live feed is really critical for rbp to reach their potential size, since they grow so fast I think the added nutritional value of live is needed, and mostly overlooked for so called healthier, safer foods.
